Last I read IBM was one of the big companies pursuing R&D in quantum computers and such plus they have some software stuff like crimestat and the weather channel under their umbrella.
If space isn’t an issue, getting a cheap office surplus machine like a Dell Optiplex SFF line for ~$100 US vs the USFF so that it supports low profile PCI-E for a hba card for more storage, or nvidia quadro p400 for better encoding at like $30-50.
It will probably use a bit more wattage, especially with more HDDs, but still should be around 50w idle for even the old systems.
I called my ISP after they bumped prices by $5/month (and told me a single time on the fine print at the bottom of the PDF e-bill of their shitty app). I threatened to switch to their competition and they told me flat out “no you won’t they’re not as fast and you’re not going to break even on setup fees for years”.
